ATTORNEY Patented Apr. 25, 1933 LUTHER T. VELEN, OF CHE-SWOLD, DELAWARE sHooK HANDLING MACHINE Application filed Jul 6, 1929. Serial No. 376,463.

This invention relates to improvements in stock handling machines, and it consists of the constructions, combinations and arrangements herein described and claimed.

,The foremost object of the invention is to provide a wheeled vehicle equipped with a pointed shock supporting beam which is designed to be thrust into the shocks as found in various situations on the field, thus to pick them up one by one preparatory to transporting'a load of the shocks to a point of dis posal.

Another object of the invention is to provide a machine for the purpose described having facilities which are briefly enumerated as follows: first, to provide means for moving the shocks rearwardly and retaining them on the shock-supporting beam; second, to afford improved means for hoisting the load; third, to provide improved means for adj usting the height of the shock-supporting beam; fourth, to introduce in a motor-propelled machine arrangements whereby the tractor is used to steer the load as well as to relieve the weight on the front wheels; fifth, to embody instrumentalities whereby the tractor motor is used to furnish the necessary power for operating the various devices;

sixth, to supply means for reversing the machine; and seventh, to provide ample clutching surfaces and associated automatically operative unclutching facilities.

Other-objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which 4 Figure 1 is a side elevation of the machine, the shock-supporting beam being shown in theraised position that it would assume if loaded, the compressor mechanism still being elevated;

nism by which the shocks are pressed together embraced by a single so thatmore may be lad. y Reference is made to the draw ngs: The

shock-supporting beam, generally designated 7 1, actually comprises a main beam 2 and an auxiliary beam '3'. The latter mayor may not be used, depending entirely on the height The main beam 2 is pointed at 4. i It is composed of an elongated metallic structure J cro'ss-sectionally formed into the shape illustrated in Figure 2. .This includes a top rib" 5 which arises from shoulders 6 that merge into flaring sides 7. These, in turn, merge into parallel portions which end in flanged troughs 8,'the purop'se of which is to act as platforms to assist in supporting the shocks which are impaled the shock-supporting.

beam.

As is observed in Figure 2, said beam defines ahousing. It isby th s housing'that a segmental worm gear 91s largely contained.

.It has an axle lO by which itis ,pivotally mounted. It carries an arm 11 upon whicha carrler wheel 12 1s Our-naIed. fThe purpose of the wheel. s to assist in ra1s1ng and lowering the front of the shock-absorbingbeam'l. To the latter end, a worm. 13 meshes with the gear 9. This worm is carried by a shaft '14 which has connection with a square or other non-circular telescopic shaft 15 through a universal joint 16. This shaft has a universal joint connectionl'T- with a driver 18 "(Figures 1,9,18 and) which'has associated with it certain unclutching mechanism by which the driving power is disconnected when the shock-supporting beam 1 reaches the limits of its raising and lowering movements.

Adjustments of the wheel 12in respect to I the gear 9 are made possible by. adopting any conventional slot and fastening bolt arrangement, for example, as illustrated at 19 in Figures 1 and 3. This same arrangementmakes itpermissible to reverse the gear 9 end for end. In turning the arm 11 upon its axle 10 Should wear of the teeth become noticeable, the gear can be reversed in position as ust indicated. It is also proposed to reverse :the

position of the gear in respectto'the front and rear of themachine. For example, when so reversed, as indicated by Figure 3, a slightly better lifting effort can be exerted especially when the machine is operated upon soft ground, With the arrangement in Figure'3, the natural forward motion of the'machine will assist the gear 9 and wheel 12 in lifting the front end of the shock-supportingbeam 1 with the load.

Arms 20 are attached to the auxiliary beam 3at 21 at a point approximately midway of its points of connection with the brackets 22 (Figures 1 and'6) atthe' front and with a pair ofoutside vertical standards 23 at the rear (Figures 1 and The purpose of the only the upper quarter of the gear. isused. 3

arm 20 is'to-; furnish a mid-support for the auxiliarybeam 3'to prevent sagging under a load. The connection 21 is ordinarily a fixture but will act as apivot. when thenecessity for making adjustments of the auxiliarybeam relatively to the main beam2 arises. At such n time, the 'rear. connecting studs 24 will be screwed into appropriateones of. series of holes25 in the vertical standards.

Also under that circumstance, the.

shoulders 6 of the main beam 2, through which slots the brackets extend, as shown in Figure 6-. A bolt 27 is inserted through the then registering holes to fix the adjustment. A

bushing 28, assembled on the bolt' between V the insides of the top rib 5, prevents compressing the former. The brackets22 have "ears 29 at the upper ends extending both forwardly and rearwardly. The former are I 7 front brackets 22 will he slid in slots 26 in the.

permanently secured at 30 to the extension point31 of the auxiliary beam. The latte-rare temporarilyv secured at 32 to the'auxiliary beam. In removing the extension point 31, v which is done-at times, the brackets 22 and other carried, parts will be removed vvith it.

The primary purpose of the extension point 31, as well as of the auxiliary beam 3, is to adapt the machine to "exceptionally .tall

shocks. )Vhen the machine is so adapted, it

becomes necessary to support the front extremity of the extension point. A telescopic elbow 33 (Figures 1 and 4) which is pivotally connected to the point 4 of the main beam and to the point 31 serves the purpose. This also acts as a guard, preventing corn stalks from entering the space between the main and auxiliary beams at the front. While on the subject of the extension point, it is to be noted that this carries a book 34 at the front. This is intended to receive and support an angleiron 35. This iron extends transversely of the machine when used, and it will be used only when the machine is fully loaded with shocks and then inserted in the hook .34, in which position it will be held by the pressure of the shocks. j

The main purpose of the angle-iron is to straighten the load prior to the discharge thereof at the point of disposal. The shocks will almost always assume a forwardly inclined position in reference to the shock-supporting beam 1 due to the fact that the bottoms of the shocks drag slightly on the ground, in the forward propulsion of the machine. Just prior to discharging the shocks, the angle-iron 35 will be inserted behind the hook 34 and the machine reversed, whereupon the same dragging tendency of the bottoms of the shocks on the ground and the rearward prese sure of the angle bar will straighten theload so that the shocks will stand upright.

Sometimes the auxiliary beam 3 and its point 31 will be removed entirely from the machine, as when handling ordinary and short shocks. But under such circumstances, it would not be impracticable to leave the auxiliary beam 3 on the machine, although at such time the extension point 31 and its appurtenances would be removed. The auxe iliary beam will be let down upon the top rib 5, the latter fitting into the former.

The front end of the auxiliary beam would then be secured by the bolt 27. Under the same condition, the rear end of the auxiliary beam is vertically adjustable along the standards 23 which are conformably struck on the arc to a circle centered upon the bolt 27. Such adjustmentis especially useful when the machine is used as a shock horse. I I

The rear end of the main beam 2 is secured at 36 to the lower ends of the outside standards 23 F igures 1 and 25). A strut 37 braces the shock-supporting beam 1. This strut preferably, although not essentially, comprises a rectangular tube which is flattened at 38 at the rear end (Figure 25) to fit between a pair of inside vertical standards 39 which are adjustably secured to the frame member 40 (Figure 17) of the tractor,

generally designated 41. The adjustments equivalent, provides a pivotal connection of the main beam 2 with the strut 37..It is upon this pivot that the shock-supportlng beam 1 canbe adjusted for variable elevations V of the front and rear with respectto" the ground. When so adjusted, the, outside standards 23' will ride alongside of the in:

sidestandards 39. I The inside standards are struck on the arc of a; circle of which the pivot is the center. They are bored. with a series of holes 46 (Figure25) across which a pin 47 is-placed upon which the rear end of the beam will rest. .A pin 48, set. acrossother series .of holes both in the outside and the inside standards 23 and 39, engages the auxiliary beam 3 to preventthe shock-supporting beam from jumping up at the irear.

Situated above the shock-supporting beam 1 is a compressor mechanism generally designated49. This comprises a pair of side bars 50 (Figures 1, 9, 17, 18 and 25) which are right-'angularin cross-section and are so set in blocks 51that the apex'es of the angles are directedjinwardlyh These'apexes are thus, capable of pressing-into the shocks,-

indenting them somewhat'so that they .will be held up in position. While on this point,

it is to be observed thatthe edges of flanges.

52 which are formed along the bottom of the; auxiliary beam 3 are sharpened by bevelling them under, the purpose of the sharpening also being to indent a sufficient number of the stalks inside of the shocks and' alsoto:

assist in .their support. i

. The blocks 51 are the mountings by the side bars 50 are slidably carried. The

blocks, in turn, are mountedupon a cross-bar 53, the ends of which are bent down, then rearwardly,'and flattened at 54 to provide load and releasing it, respectively. A square medial portion 57 ofthe bar 53 is received by brackets 58 which are adjustably carried by the outside vertical standards 23 (Figure 25). Vertical adjustment of the rear end of the compressing mechanism is desirable/for.

different heights of shocks. The bar53 is permanently affixed to the brackets 58, and

that end the square, portion 57 may be Weld-" ed thereto.

. Lateral adjustment of the side bars50rel l atively to the longitudinal centerof .thema-- chine is accomplished by inserting cotter pins 59, or equivalents thereto, in appropriate ones: of series of holes 60 near the ends of the.

bar 53. Longitudinal sliding .movement of stop pins 61 (Figure which are insert-' the bars in the forward direction is-limited' by the engagement of the blocks 51 by able in any one of a series of round holes 62 in the lower flange of each-ban, On the-same principle, stop pins in'sertedin these holes 7 in front of the blocks 51 can be used to limit 7 rearwardsliding of the side bars. The up per flanges of the side bars are equipped with square or other non-circular holes 63. These have several purposes. The tines 64 (Figures 9 and 23) are secured in these holes for the purpose of preventing theshocks from slipping down. The number of tines to be used will depend upon circumstances; When loading, relatively few will be employed, and

these near the front of the compressing mechanism. YVhen using the machine to impale an entirerick of shocks, for example, as in re-loading, numerous tines maybe fitted upon the side bars 50, even at the base or rear end,

because then all of the shocks will be in-line and the compressor mechanism can be let down upon the shocks with comparative ease, the tinesnot: interfering The inclination and'length of the tines will be subject to dis-' crimination in the operation of the machine. Another purpose of the holes 63, at least of the series in one of the side bars 50, 'is, to provide places of attachment of an angle bracket 65 (Figure 7) to which a straight or curved span bar 66 is adjustably secured at 67. This span bar serves the purpose of holding the shock under compression when the machine has'been filled up to the point where the span bar appears in Figure 1. The

span barcan be removed from the bracket 65 and manuallyset at any desired point across the compressor mechanism. For this purpose, the span bar: has racks 68 near each end, with notches that agree in inclination withxtheupper flangesof the side bars. These racks are set over'the edges of the flanges, and compression is gotten-by use ofa compression lever 69 (Figure 8).

The hooked point 7 0. of this lever is in-v serted' in the most convenient one of either series of holes 71in the top of the span bar,

and the shoulder 72 of the lever is applied against the side bar sothat the heel 73 engages the lower flange. Downward pressure upon the leverwill pull the spanbar over so that the successive notches of one of the racks engage the adj oiningside bar. The lever remains inplace' until it is desired to remove the span bar. In the instance of the span bar being attached to 'the bracket 65, as in Figure 7. only the remoterack 68"will be operated in connection with one of the side bars, thev rack nearest the bracket being idle at such time. One end of the span bar is'pointed at 74 so that it can more readily be thrust through the load across the compressor mechanism.. w 1 A second purpose-of the round holes 62 5O are susceptible. will be compensated for, especially when the rope compressor 7 7is set at points-farther forwardly than indicated in Figure 1; 7 The hood 262, carried by the compressor 77, is inclined upwardly and forwardly for the purpose of sliding over a shock and automatically raising the compressor 19.

upon afforw'a-rdmotion of'the compressor. It is'by means of therope compressor 77 that the side bars 50 are mechanically drawn together in the usual operation of forming a load. During this operation, the sidebars 50 are brought-together from time to time to squeeze the shocks into a straight line. sometimesisome of the shocks will be out of line, as, for example, WhenJthe operator fails to impale the centeriof the shockswith the point f of the beam 1. Under this condition, it is a function of the rope compressor 77to center't'he load so that it will not topple to one 7 side'or the other. w

For the above stated purpose, the bars 78, and 7 9 (Figure 23) carry adjustable stops 81 and 82 which limit the distance to which the side bars 50 can be moved either toward" the auxiliary beam 3 or the top rib 5, depending upon which conjunction the compressor mechanism is used with. The stop 81 is attached to a guide arm 83 that forms part of the bar 79 andboth Tests and "rides u on the auxiliary beam 8, assuming thisto be in use as shown; An extension 84 ofthe stop 81 reaches across the beam 3 and abutsthe stop 82 to prevent the stops from closely contact- I ing the sides of the'beam and interfering with the free sliding motion'of the beam. I v Pairs of ropes 85, 86 and 87, 88 (Figures 17, 18, 23, 25 and 27 respectively close. and

separate the side bars 50 of the, compressor mechanism. Taking the ropes in the order oft-heir designation, one en'd'of rope 85 is wound over the top of oneextreniity of the drum 56 and secured, the other end passing over alower pulley 89 (Figure 23), through a slot in the'block'76 and tied to the eyebolt 90. One end of rope 86 is wound over the top of the other extremity of the drum 56 (Figure 27), while the forward end passes around a' lower pulley .91 (Figure 2 3),, through a slot in the adjacent block 76and tied'to the eye-bolt 7 5'. Thusit is seen that the forward ends of the ropes 85 are crossed and secured to the opposite bars 50. The rear end of rope '87 passes around a pulley 92, is wound on top of an inner portion of the drum 56 and secured, while the forward end of the rope passes around an upper pulley 93 and is tied to a stud 94 on the bar 7 8.

The rear end of rope 88 passes around a pulley 95, is wound over the top of an inner portion of the drum 56 and secured, while the forward end pass-es over an upper pulley and is tied to a stud 97 onthe bar 79.

The winding upon the drum 56 of the pairs of ropes described isopposite so that turning of the drum in the direction of the arrow 98 (Figure 27) will wind up the pair 85, 86 and unwind the pair 87, 88, thus to exert inward pulls upon the side bars at the points 7 5 and 90 and by thus closing the side bars 50 exercise acompression upon the load. Figure 27 illustrates the closed position. Upon turning the drum 56 in the opposite direction, there will be an unwinding of the pair 85, 86 and a winding up of the pair 87, 88 so that inward pulls are exerted upon thebars 78 and 79 at the points 94 and 97, causing-separation of the side bars 50 and a release of 60111 pression.

Raising and lowering of the mechanism is accomplished by a pair of ropes 99 which at one end are wound over the top of the medial portion '01": the drum 56 and secured, and at the other ends are secured -to eye-bolts 100 on the side bars 50. These ropes are guided over pulleys 101 mounted upon the upper extremities of the outside standards '23. Raising of the compressor mechanism is accompanied by a separation of the side bars 50. Lowering of the compressor mechanism is accompanied by a closing of the side bars, this act producing the compression upon the load. previously alluded to. T

.Assume that the machine has either been filled with shocks up to the point of the compressor 77 or that a shock has become stuck somewhere along the beam. In either case, the following would be the procedure: The compressor mechanism 4-9 will be lowered by turning the drum 56 in the direction of arrow 98 (Figure 27). The winding and un winding of the respective cable pairs 85, 86 and 87, 88 will lower theside bars 50 over the shock or shocks. 7 The front shock defines a point of resistance against which the rope compressor 77 acts. Continued turning of the drum 56 exerts forces upon the arms 78 and 79 of the compressor 77, which, in coaction with the point of resistance, cause the closure of the side bars and compression of the load. Further centinued turning after the limit of compression is reached will pull the entire compressor mechanism rearwardly, causing the compressor 77 to force the shock compression or shocks. rearwardlyagainst the standards 23and39 Turning of the drum 56 oppositely to the arrow 98 moves the entire compressor mechanism forwardly, causes separation of the side bars 50, and raises the compressor mechanism-49 tothe original position-inFigure'l. The first and third of these motions are accommodated respectively 1 by: the slidable mounting of the bars 50 within the blocks 51 (Figure 25) and .by the rockable'niounting' of the blocks upon the cross-bar 53. The second motion, wherein the sidebars separate, requires pivotal mounting'which a bolt 102 affords. This bolt (Figures 9, 10, 11, 18 and 27) occupies slots 1013 and 104 in superimposed bars 105, 106 which it loosely connects.

Theside bars 50 are permanently connected to the respective bars 105 and '106 by brackets 107, 108, the latter extending under to apoint of connection with the bar 106. Pairs of stop'bolts 109'and 110 are adjustably fitted in the slots 103, 104, the purpose of these being to limit the closing and separating movec ments of the base of the sidebars 50.- Figure 11 shows certain ones of the stop bolts brought intoplay to limit the closing. movement.

Figure 10 illustrates a position approximate ly half-way between the extreme movement's.

It is to the respective sidebars that the pulleys 92 and are connected. Itis the action of the ropes 87 and 88 upon these pulleys that pulls the superimposed bars 105,

106 as well' as the side bars 50 forwardly upon the aforesaid reverse-turningof the drum 56. 'It is during the forward movement of thebars'105, 106' and 50 by virtue of r the winding of the ropes 87 and 88 upon the inner endsof the'drums 56,a'n'd somewhere near the endof such winding, that the hoist-f ing ropes 99 will reverse inposition in respect to the medial portions of the drum and begin winding up on their own account. It .is the winding up of the ropes 99 from beneath the drum 56; during forwardturn'ing that tension is applied at the points 100 and the for-' ward end of the compressor mechanism is raised. The wound ropes 87 and 88 also exert a tensionat the points94 and 97, thus aiding the ropes 99 in the raising efl'ort. I

I Reverting to the act of compressing the load by virtue of the rearward movement of the compressor 77 a condition is conceivable under which the compressor 77 may'necesropes 99'as the compressor 77 approaches the standards,-an'd thereafter the rope'will slipfdown upon :the tapers 111, producing enough slack in the ropes 99 to prevent the aforesaid undesirable raising. If the ropes 99 ,cOntinuedrunder tension, they would'raise the front end of the compressor mechanism, but the recesses-afforded by'the tapers 111 permit the ropes to slacken so that the forward endwillnotraise.

C-A's'p-ring 112 :(Figure connectedat its opposite ends to the side bars or some extensions thereof, tends to draw the base ends of the side bars together. In. doing so, the spring tends to abut one of each of the pairs of stop bolts 1'09, 110'with'the pivot bolt 102, asshown in'Figure 11. The most important function ofthe spring is to keep the rear end of the .load'under compression, and when exceptionally large shocks areforced into the base end o'f'the compressor mechanism, the spring yields so that the side bars 50 can readily adapt'themselves. I Y

" A cable 113 "(Figure 2 5) carries a pin 114 at one end, intended for insertion in a hole in the middle section 1150f the drum 56.; The

sole purpose of thiscable'is to provide a sup- T port forthe rear end of the .tnain beam 2 while fixing the adjustment of this in respect to the abutment standards. Even when the main-beamis'not under load it is sufficiently heavy to warrant the provision and use of the cable 113; '1 The end remotefrom the pin 114-is tied .to a hp 116 extending from the top'ribg5, and upon giving .the drum 56 a turnorso, the main beam will be held lifted until the operator has inserted the pin 47 through the desired holes. It may also prove necessary at times to'use the cable 113 while the beam has a partly formed load bearing down thereupon. The operator may see the necessity of then making an adj us'tment.- All he has to do is. to tie the cable 113 on and connect'the pin 11'4with the drum, turn the V latter, as stated, and raise" or lower the main beamas vmuch as necessary. The cable is trained over aroller 117 which is carried by the sta'ndards 39 and serves the added function of a spacer for the upper extremities.

-;-'The front extremities of the side bars 50 are outwardly flared at 118 to facilitate the entrance of the last shocks after the side bars 50' have been lowered priorto the final compressing operation; Pivoted uponb0lts119 upon the side bars 50 slightly tothe rearof the fiares1-18 are retaining levers 120.

The same function isobtainable by said le versuponia reversal of the machine,but this at'the sacrifice of two shocks unless the supplemental is used.

Enlargements 136 of thelevers' 120 through which the pivots 119 extend have sets of 7 holes 137 toreceive stop pins 138 (Figures 9 and 12) which are engageable with the out 1 sides of the bars 50 to limit the movement of the levers in one direction. The'levers are resiliently mounted upon thepivots 119, that is to say, springs 139 (Figure 13) are-socombined with the levers and side bars that the back prongs 122 will tend'to normally assume a crossed position. The passage of a shock past the back prongs will obviously open them, but the tension of the springs139 will restore the prongs to-the original position,

The stoppins can be set in any one hole of the sets of holes so as to regulate the amount of extension of the back prongs compressor mechanism. 7

Originally the levers 120 stand :in'reference to the side bars 50 approximately as shown'in full lines in Figure 9. At this particular time, the side bars 50 are suspended across the well above the shocks so that no part of the compressor mechanism 49 will interfere with the shocks as they are threaded upon the main beam'l. It is not until the load has been completed approximately up to therope compressor 77 that the compressor mechanism will be let-down for an initial compression of the loadby means of the compress0r;77. At such time, the levers 120 will assume .the dotted line position 126 (Figure 9). Succeeding shocks picked up by the machine will pass the then crossed back'prongs 122, making room for approximately two shocks. The foremost one of thesewill be held in the receptacle 124 already referred to. other but'last shock can be carried by the main beam in front of the now crossed front prongs 121' provided it is intended to propel occupy the position 127 -(l Tigure'9).v The Still an- I the machine forwardly-" Such'shock would I forward motion ofthe machine presses the shock betweenthese prongs, tends toseparate the points, and in doing so, will exert inward pressures upon the forward extrem ity of the bars 50, looking these closed.

A similar function obtains upon a reversal. .gof the direction of the machine when the shock foremost of the load will similarly exert pressure against the now crossed back prongs 122', The separating, eflect upon these prongs will produce .inWard,pre ssures uponthe side bars/50, locking these in the manner already indicated. [But ordinarily,

If a shock were admitted to the receptacle the advantage of the automatic locking function must be had at the expense of two shocks.

My result in the loss of the foremost'shock because up to this time the shock in frontvof the rope compressor 77 is quiteilooselysituated. But this does notmean that advantage cannot be taken of the receptacle 124 nor of the crossed front prongs 121 for the holdingof two additional shocks upon a reverse operation of the machine. V

Under such a circumstance, use would be 0 made of the supplemental compressingdevice illustrated in Figure 14. This comprises a rope 128, hooked at 129 at one end to a short chain 130 which, in turn, has a hook131 intended to be fitted over one of the side bars 50. The opposite side bar carries a pulley 132 to which the rope is applied before it is threaded through one of the links of' the chain, then carried back again to a drum 133 situated a requisite distance from the pulley. The free extremity of the rope carries astout needle 134 which is used as a lever upon the drum after all available rope has been wound thereon, to forcibly wind up the rope on the drum and pull the rope taut across the front shock. It is by this means that the front extremity of the compressing mechanism is manually secured.

Supplemental compression can be had anywhere along the shock-supporting beam, and it is not always necessary to equip one of the side bars with a drum on which to wind the rope 128; But it is necessary to equip one of the beams with apulley 132 wherever it is intended to use this device. i

the ropes 128 with their hook and needle accessories 134 will beused. Application will be made as pictured in Figure 30. Both hooks 131 will be appliedto the inner side bar 50. "The right rope 128 will becarried through the load, applied to an extra pulley 135, and the needle 134 will be thrust into the most convenient shock. The left rope 128 will be carried in front of the foremost shock and applied to the pulley 182, which we will assume is situated somewhere between the compressor 77 and thefront ofithe compressor' mechanism, and the otherwise, loose needle 134 is then laid crosswise of the pros truding end of the inserted needle and is turned around that end. This causes both ropes to be woundu'pon the protruding end of the needle, and the action is to compress the load by drawing-the side bars 50 together.

' This keeps the load from sliding off.

Attention is now directed to the mode of propelling the machine as well as applying the power to various mechanical contriv-, ances previouslydescribed. A tractor frame comprises the foundation of the niachine; This frame comprises longitudinal components 141 which at the forward end terminate at the frame member 40 previously alluded to (Figure 17). At this point 5 these membersare secured by means of Under a condition such as this, a pair of brackets 142 toan'axle bar. 143 whi'ch at its ends pivotally carries stub/axles l44jupon which the tractor wheels 145 are mounted.

A caster 260' has appropriate bearing on'the rear extremity of thetractor frame. Immediately above the axis an' adjustable rest 261 which is adapted tolsuppojrt'the side bars 50 of the compressor mechanism 49 when the latter is displaced rearwardly' for the vpurpose of clearing the machine foraction-to dislodge ashock'on the point of the main beam, also for the purpose of more nearly balancing the machine upon the tractor wheels;145 preparatory to turning the machlne upon the axis, using one'of the tractor wheels as a pivot. A hand wheel 146 (Figreach bar 7150 which has, pivotal connection with corresponding inside plates;

At the-rear end the tractor frame has lateral components 151 upon one extremity of one set ofwhich the engine 152 is mounted. The engine is either equipped with an exceptionally long crank shaft or the latter is suitably connected with a main drive shaft 153 from which the three. drives previously mentioned are taken. For the compression of theload as well as theperformance of the incidental operations of which the drum 56 is capable, the latter carries a worm gear 154 upon one of its trunnions 55 (Figures .25 a

and 26). This gear is encasedat 155,-and the casing provides a bearing fora worm 156on the forward. end of a cross-sectional non-cir-. cular telescopic shaft 157. The rear end of this shaft has ample bearing in a rather long sleeve 158-.which is part of a yoke-159 (Fig ures 15 and 18) which is journaled upon bushings 160 of bearing brackets 161 in which the shaft 153 has partial support. The vertical adjustments of which the rear end of the main beam 2 are capable as well as the minor adjustments of the cross-bare?) injrespect to the outside standards 23. are compensated for by the telescopic shaft 157 and the rockably mounted yoke 159 andr bracket 155.

v A gear 162 on therear end ofthe shaft 157 mesheswith pinions 1:63, an d 164 loose on the shaft 153 (Figure 15). These pinions have clutch hubs 165 with 'either of which the clutch element 166,'splined on the shaft 153, can'be engaged by the fork167of apivote'd lever. 168 (Figures .9 and18). Itis assumed E turn the drum 56 inthe direction of arrow 98: (Figure 27 to cause lowering of the com- 1 pressor mechanism from the position in Figure=1 to a position for compressing a load. Reverse shifting of the lever 168 will clutch tle' pinion 163 to the shaft 153 to the reverse e ect.

. .Nextin order is the hoisting drive. This drive hoists the entire front end of the machine from proximity with the ground either during the process of forming a load or after a- -complete load has been formed, It acts directly upon th'eworm' gear 90f the. carrier wheel 12. -The rear end of the driver 18 (Figures 16,18 and 20) fiXedly'ca-rries a gear 172 which has a concave web 173.' The gear meshes with pinions 174 and 175 that are journaled uponbushings 176 (Figure of bearing brackets 177. The shaft 153 has bearing in these bushings. A clutch element 178, splined on theshaft 153, is engageable with the clutch'hub 179 of either pinion, A

.lever180has a fork 181'by which the element 178 is shifted. .The lever is pivoted upon a stud 1.82 (Figu're and at an appropriate 'd-istancefrom the pivot has a tooth 183 meshing witha stationary rack 184 (Figure 18) g The lever 180 has a resilient quality. It is designed to beput' under tension by the act of moving it either forwardly or rearwardly in order to clutch-one or the other of the pinions 174, 17 5 to the shaft 153.] The-tension stored in thee-lever under this position, in

This inherent qual tooth 1-83 with therack 184, later becomes the agency bywhich' the leveri180, and consequcntly the clutch element 178, is automati cally restored to the neutral positionindicat- .ity of the lever is directly attributable to the vertical component 185 (Figure 20) whichv extends parallel to the pivot stud 182. This clement178 is intended to occur when the gear 9 has been turned to'its extremities of component-is'subject toa degree of torsion,

i due to the fact that the-lever has bearing on the stud 182' at two points and that these ,points are noticeablyseparated. The automatic neutralization of the clutch raising and lowering movements of the front end of the machine. For thesepurposes, the driver18 has a left-hand thread 186 (Figures 9,18 and 20) by which a cam 187 is moved back and forth in reference to a fixed guide 188 whenthe driver 18'is turned in one or the 'otherdirection. The cam has a key 189 which (arrow reverse propulsion of the machine. -ing of the lever 203 in the forward direction' (Figure 18.) will engage the'element 200 effect.

front-and rear ends are bevelled to facili- V tate the lifting of front and rear lugs 191,

192 that are secured to the lever 180 by thumb screws or-a suitable equivalent. The thumb screws afford adjustments of the lugs lengthwise of the lever so that the range of raising and lowering of the front end of the machine can be regulated.

One of the lugs, namely, the front lug 191,

is shorter than the other. The long lug 192 has a recess 193 on the under side (Figure 21) so that the cam 187,will return to its original neutral position, assuming it to have been propelled to a point past the left side of the rear lug 192 by an operationv of the lever 18.0 to additionally lower the machinemore than a given setting providesfor, and this without the striking of the lug 192 by the cam 187 on its way forwardly into engagement with the front lug 191 which: is then positioned in readiness foran automatic neutralizationof the lever 180. The operation of the lever .180 alluded to comprises a bearing down upon the lever 180 after it has been shifted rearwardly for a lowering of the front end .ofthe machine. This shifting of theflever is followed by a rearward travel of the cam 187. VVhen' this is about to reach the rear lug 192, the operator will press down on the lever, as stated, thus giving the. lever enough of a twist upon its pivot 182 to raise the inner end of, the lug 192 out of range of the cam. The cam can then pass rearwardly of the lug 192, and the additional turning of the driver 18 thus represented is what produces the additional lowering of the machine not provided for by the initial setting of the'lug 192.

Pinions 194, 195 having attached clutch hubs 196 and being loosely mounted on the main drive shaft 158, respectively mesh with the gear 197 and reverse pinion 1980f a differential mechanism 199 (Figure 19). The

which, in practice,are connected with the differential case of a conventional diflerential mechanism. "Clutch-elements 200 and 201, splined and slidable on the shaft 153, are connected by a yoke 202 which is slidable by a lever 203 to produce forward or with the hub 196 of the pinion 194 causing forward propulsion of'themachine; -A. shift of the lever to the. rear will'have the reverse The d-etailsof the differential mechanism 199' are not herein disclosed but inpractice -will be like any known differential mecha- Shift a sprocket 209 to which it isalso applied. The counter-shafts have bearing on the axle bar 145. The inside plates 149 carry guards 212 which extend around the fronts of the wheels to avoid tearing of the mud lugs on the wheels into the cornstalks when turning the tractor.

A fly-wheel 214 has stabilizing effect upon the main shaft 153. A hearing 215, situated .intermediately of the pinions 194, 195, has

its support upon the transmission housing 216 and provides a very necessary support for the shaft 153 in the region of the pinions mentioned because it is upon these that great strains are put in delivering the propelling power to the tractor wheels. Brake drums 217 on the shafts 204, 205 have individual levers218, 219 for their operation (Figure 18).

Attention is directed to Figure 28 which discloses a so-called double leverage compressor mechanism. The View is an inverted plan. The arrangement of the ropes and pulleys is intended to produce parallel closing and opening motions of the side bars 50. The drum 56 has ropes 220 and 2-21 wound thereupon, the rear ends of each of these passing over double pulleys 222, 223 as well as single pulleys 224, 225 to points of connection 226, 227, respectively, made with a guide 223 V and one of a pair of arms 229, 230 which extend in one direction from one of the side bars 50. The other side bar has a similar pair of arms 231, 232 which extend in the other direction. The pairs of arms overlap and are slidable relatively to each other.

7 The forward ends of ropes 220, 221 pass around double pulleys 233, 234, respectively, carried .by a front guide 235 and the arm 230, then around single pulleys 236, 237, respectively carried by the arms 230, 232, finally ending at points of connection with the guide 235 and arm 230. The ropes 238, 239 of a second set respectively pass over the double pulleys 222 and single pulleys 240 to a point of connection with the guide 228 and over the double pulley 223 and a single pulley 241 to a point of connection with the arm 229. The front ends of the same ropes respectively pass over the double pulley 233 and a single pulley 242 to a point of connection with the front guide 235 and over the double pulley 234, around a single pul- I ley 243 to a point of connectionwiththe arm 230.

The purpose of the sets of ropes 220, 221 and 238, 239 is to spread and contract the compressor mechanism with a parallel motion, the drum 56 being turned either in one or the other direction to accomplish these purposes. Figure 29 illustrates a further modification of a so-called triple compression mechanism. The motion of the side I quarter circle.

bars 50 is somewhat on the order of those in Figure 27 Either-end of the compression mechanism can be closed to exercise acompression upon the'load. For simplicity in illustration and description, only one set of ropes is shown, but in practice the ropes illus trated in Figure 29 will be duplicated in order to properly perform the functions described.

A'rope 244 is wound upon the drum 56, and has its rear end trained over single pulleys 245 and 246, respectively oarried by the arms 247, 248 of' the" side bars 50, passed around a double pulley 249 carried by a rear guide 250, extended forwardly and passed around a triple pulley 251, twice around a double pulley 252, oncearounda second triple pulley 253, and finally connected at 254 with one of the'side bars 50. The forward end of the rope 244 is passed twice around both the triplepulleys 253 and 251 before being extended rearwardly forpassage around the double pulley 249 and finally connected at 255 to the same side bar 50. It will be borne inmind that with a duplication of the rope arrangement the ends of the companion to the rope 244 will be attached to the other side bar50. T he: front triple pulley 251 is carried by a guide 256. The double pulley 252 is care ried by one of a pair of arms 257, 258which correspond with the arms'247,248. A proper turning of the drum 56 will close either the front or rear end of the compression mechanisml v The operation of the machine is asfollows: Assume the field to be dotted withshocks as set up during harvesting. The shocks will be checked; that is to say, will stand atregular intervals apart. A pin will be set in one of the holes 259 of the quadrant 148 so that after a determined number of shocks have been speared by propelling the machine in a forward direction, a subsequent-turn of the hand-wheel 146 and a corresponding turn v of the machine in approximately a quarter circle will bring the pin into stopping engagement with the axle bar 143 and the ma- 7 chine in a position approximately from that in which it started in readiness to unload the shocks in rick formation.

To load the machine, adjust the rear end ofthe beam 1 to the requisite height'above the ground. This adjustment is determined by the run of the shocks. Low shocks must have a low adjustment of the beam 1, and vice versa. Lower the front end of the beam by 1 pulling the lever 180 (Figure 18) rearwardly. This causes the worm gear 9 to revolve clockwise (Figure -1) for approximately a, The cam 187 travels rearwardly at the same time, and when it engages the rear lug 192 will flex the lever 180 so that the tooth 183 is raised clear of the rack 184, permitting the stored tension in the vertical .ciimponent'lh (Figure 20) to automatically returnut-he l'everi and the clutch element 178 ';:(Fig1-1re 1-5). to the neutral position. Shift the .lever 203 forwardly. This engages the element 2001'(Figure.15)' withthehub, of the fpinion'194=topropelthe machine forwardly.
